CryptoLocker, a new ransomware malware, began making the rounds several months ago. This ransomware is particularly nasty because infected users are in danger of losing their personal files forever. Cryptolocker is spread through malicious hyperlinks shared via social media and spam emails, like fake UPS tracking notification emails. The original demanded payments of $100 to decrypt files, but the new and improved version demanding $300 from victims.
Apparently, the encryption is created using a unique RSA-2048 public key. The decryption key is located on a secret server somewhere on the Internet and then there is a countdown on the infected machine which will let you know how long you have until this key will no longer be available.
So the only way to be safe is not getting affected. Here are a few softwares which can prevent cryptolocker attacks.
